What does a circular motion with the arm typically signify?

A circular motion with the arm is a commonly recognized signal indicating that the load should be rotated. This gesture effectively communicates to the operator the need to turn the load around a vertical axis. This signal is crucial in various lifting operations where precision and control are required to orient the load correctly without causing accidents or hazards.

In lifting operations, other signals have distinct meanings: lowering the load typically would use a downward-directed motion; stopping the load would involve a different signaling technique, such as holding the arm out to the side; and raising the load is usually signified by an upward motion. Understanding these signals is vital for the safety and efficiency of construction and lifting activities.
